My finacial responsibility

When I failed to settle on a home. I was informed that not only can the seller sue for damages but that we are liable to the realtor for the closing costs. I wanted to know how is it possible to be liable to the realtor for the closing costs when they were acting in a dual agent capacity and still stand to make money from the sale of the property.

Did you ask the Realtor?
You see, because you defaulted, they did not get their rightful and earned real estate commission.
Therefore you are liable for this commission.
